	ChangeLog objfiles.c objfiles.h symfile.c target.c main.c
	Makefile.in configure.in
Added Files:
	os9kread.c os9kstab.c remote-os9k.c

        * os9kread.c: New file to read os9000 style symbo table.
        * os9kstab.c: new file to read os9000 style stabs.
        * remote-os9k.c: remote protocol talking to os9000 rombug monitor.
        * objfiles.c (find_pc_objfile): new function to search objfile
        from pc.
        * objfiles.c (objfile_relocate_data): new function to relocate
        data symbols in symbol table.
        * objfiles.h: Add two aux fields in struct objfile to handle
        multiple symbol table files situation like in os9000.
        * symfile.c: Change so 'symbol-file' command can handle multiple
        files. Also call target_link() to get relocation infos.
        * target.c (target_link): new function to get relocation info when
        a symbol file is requested to load.
        * main.c (quit_command): take out 'inferior_pid != 0' condition,
        because in cross mode there's no inferior pid, bit they need to
        be detached.
        Makefile.in: add os9kread.c os9kstab.c and .o's.
        configure.in: add i386os9k target.
        config/i386/i386os9k.mt: new add.
        config/i386/tm-i386os9k.h: new add.
